Hi friends,
Somebody might have asked this question before me and many of you might have known the answer. So please share it
It is a simple(may be stupid) question on Servlet.
At last servlet is a class and every class has its constructor. So Container must be calling that constructor in case of servlet for us.
Is that constructor really exists?
But what is in that constructor?
What would happen if we write our own constructor in a servlet?
Thank you,
Sumit

Like any java classes, servlets also have constructors. If you don't write one, there will still be the default constructor. You must have a no-argument constructor, because the container needs it to instanciate it.
You're not supposed to do anything in the constructor. Initialization should be done in the "init" method.
